GEORGE W. CRABB, OF SAND LAKE, MICHIGAN, ASSIGNOR TO FRED S. ORABB ANDJACOB S. LOCKERBY, OF SAME PLACE.

CHURN.

SPECIFICATION forming' part of Letters Patent No. 520,561, dated May 29,1894. Application filed September 25, 1893. Serial No. 486,363. (Nomodel.)

To @ZZ whom, it may concern:

Be it known that I, GEORGE W. CEABB, a citizen of the United States,residing at Sand Lake, in the county of Kent and State of Michigan, haveinvented certain new and useful Improvements in Churns; and I do herebydeclare the following to be a full, clear, and exact description-of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in churns, and its object is toprovide the same with certain new and useful features, hereinafter morefully described, and particularly pointed out in the claims, referencebeing had to the accompanying drawings, in Which- Figure l is a verticalsection of a device embodying my invention, on the line 1-1 of Fig. 2;Fig. 2 a plan view of the same with parts broken away to show theinternal construction; Fig.3 a detail of the pivot bearing of the yoke;and Fig. 4 a detail showing the construction of the yoke.

Like letters refer to like parts in all of the figures.

A represents the usual rectangular box, or vessel, having an upperremovable portion A secured by a bar B, which portion when removedpermits access to the interior of the said vessel. Upon a suitable framework L and at opposite sides of the same are knife edge supports M, uponwhich rests a yoke consisting of a transverse middle part H, whichextends beneath the middle of the box A, and two vertical portions Hembracing the sides of said box and extending upward to about `midway ofsaid sides, from whence they extend outward at H, having oppositelyinclined under sides H to rest upon the knife edges M. An armIdependsfrom the middle of said voke, to which is attached a verticallyadjustable Weight J, whereby the center of gravity ofthe device isadjusted to conform to different quantities of cream therein contained.Cleats N and N are attached to the box A at each side of said yoke,which retain said box and yoke in proper relative position, and permitof freely lifting the box out of the yoke as occasion requires; a leverK is also attached to said yoke, whereby the device is operated.

bars F', form a rack, whichis divided at the middle, and detachablysecured in the bottom of the box A, by means of a button G and spurs G.By disengaging said button the inner end of each portion of said rackmay be raised and the sections removed from the box for cleaning.

As the box A oscillates in a vertical plane the cream iiows alternatelytoward each end of the same, and is broken up and churned by flowingover the bars F', and also passes under and lifts the deflector E, as itflows in one direction and passes over and depresses said dellector asit passes in the opposite direction, this deflector further agitates thecream and exposes it to the air. Said deflector also imparts a rollingmotion to the butter after separation takes place, whereby it is in ashort time gathered into a single large roll.

It will be observed that the parts of this device are readily detachableand removable from each other for cleaning and also of simple and easyconstruction.

1. In a churn, in combination With'a box pivoted to vibrate on ahorizontal axis, a deiiector plate arranged in an inclined positionwithin said box, and pivoted near its upper end to said box, and havingits lower end detached and freely movable vertically, whereby the creamor products thereof passalternately below and above said plate,substantially as described.

2.' In a churn, in combination With a box, substantially as described,and having an openingat the top,and having vertical grooves in the sidesof the same,a removable bar pivotally mounted in said grooves, and adefiector plate attached at the upper end to said bar,

3. In a churn, in combination with a box In testimony whereof I affix mysignature in substantially as described, to contain the presence of twowitnesses. 5 cream and pivoted to vibrate on a horizontal axis, a rackdivided near the middle, spurs in GEORGE W' CRABB' the ends'of said rackengaging the ends of Witnesses: said box, and a buttonengaging themiddle J.
